`public class DebugUtils`
`extends Object` ``

java.lang.Object
↳ | android.util.DebugUtils

Various utilities for debugging and logging.

## Summary

### Public methods
`static boolean` | `isObjectSelected(Object object)` Filters objects against the `ANDROID_OBJECT_FILTER` environment variable.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Public methods

### isObjectSelected

    public static boolean isObjectSelected (Object object)

Filters objects against the `ANDROID_OBJECT_FILTER` environment variable. This environment variable can filter objects based on their class name and attribute values.

Here is the syntax for `ANDROID_OBJECT_FILTER`:

`ClassName@attribute1=value1@attribute2=value2...`

Examples:

- Select TextView instances: `TextView`
- Select TextView instances of text "Loading" and bottom offset of 22: `TextView@text=Loading.*@bottom=22`

The class name and the values are regular expressions.

This class is useful for debugging and logging purpose:

     if (DEBUG) {
       if (DebugUtils.isObjectSelected(childView) && LOGV_ENABLED) {
         Log.v(TAG, "Object " + childView + " logged!");
       }
     }

NOTE: This method is very expensive as it relies heavily on regular expressions and reflection. Calls to this method should always be stripped out of the release binaries and avoided as much as possible in debug mode.

Parameters
`object` | `Object`: any object to match against the ANDROID_OBJECT_FILTER environement variable

Returns
`boolean` | true if object is selected by the ANDROID_OBJECT_FILTER environment variable, false otherwise
